[Improve] Make Telegram task topic handoffs explicit

[daniel-lxs]

Summary

• reply in the source Telegram conversation when a task moves into a new topic
• link directly to the new forum topic when Telegram exposes a permalink
• explain same-chat fallback when Telegram rejects topic creation
• recognize Telegram bot-profile links as group invocations
• document the resulting private-chat and forum-supergroup behavior

Behavior

Before, the source message received an eyes reaction and the task topic appeared silently. A topic creation failure also silently started the task in the source chat.

After, the source conversation names the new topic and offers Open topic and Follow Task actions. If topic creation fails, the started message says why the task remained in the current conversation and points to Threaded Mode or Manage Topics.

The first preview shows the forum-supergroup variant. Private bot topics receive the same handoff, but direct users to Telegram's topic list instead of showing an Open topic deep link.
